marijuana oil

A step-by-step guide to making medical marijuana oil

The benefits of medicinal cannabis oil (from the dried Cannabis sativa L. plant, mostly the Indica variety (Kaneh Bosem)) are doubted by some people and accepted with open arms by others. Whether you are an interested skeptic or a true “believer”, just follow the steps below and find out how to make your own medicinal cannabis oil. The alternative method with olive oil is the healthiest and also the least dangerous to produce.
The following information is purely informative. If you want to treat an illness, contact your doctor beforehand to discuss the therapy.


Familiarize yourself with the terminology

Understand the difference between ‘marijuana’ and hemp.

Scientifically, the correct word is cannabis and not the racially negative connotation “marijuana”. Sativa is simply Latin for “cultivated”: as in Cannabis sativa (L). Using the terms marijuana, pot, marijuana, hash or even hemp obscures the reality and taxonomic origin of the species. Artificial divisions are created and thus the prohibition by the Ministry of Truth is upheld.

How often do we hear in the mainstream media that “hemp is a cousin of marijuana” is nonsense, and it’s willful deception into the bargain.

Plants contain cannabinoids, a group of chemicals that activate cell membrane receptors.

The best-known of cannabinoids is tetrahydrocannabinol, abbreviated as THC. To make effective cannabis oil, you need a female plant.

Understand that medical marijuana oil is not the same as hemp seed oil.

Hemp seed oil is a cold-pressed oil made from the seeds of the hemp plant. It is rich in essential fatty acids and is used for its nutrients. You can easily buy it in health food stores. The oil is often incorrectly referred to as hemp oil, which it is not. Real hemp oil (i.e. medical marijuana/cannabis oil) is made from the buds of the female cannabis plant. The THC and cannabinoids in the plant ensure that it has cellular effects and medicinal benefits.

Understand synonyms.

Medical marijuana oil is also known as hemp oil, cannabis oil, or hash oil.

Making medical marijuana oil with a solvent

Buy and dry your plant.

Buy the best quality you can afford. The better the quality, the better the oil. Make sure the plant’s buds are as dry as possible before you begin. Since it is quite laborious to make, it is recommended to work with a larger amount of bud, around 450 grams or more, but you can start with as little as 30 grams. The amount of oil you can get varies, but 30 grams will give you around 3 to 4 grams of oil on average, depending on the type of plant. When buying your plants, choose a species that contains as much THC as possible. A good Sativa strain is recommended if you want to treat a person with depression. For most other conditions, you should try an India variant. This relaxes and ensures relaxation and a good night’s sleep.

Decide on a solvent.

The solvent pulls the THC out of the plant. You need about 7.5 liters of the solvent for 450 grams of dried hemp. About 500ml of solvent should be enough if you use 30 grams of the plant. There are a variety of solvents you could use, but the most commonly used solvents are alcohol and naphtha. Pure naphtha is inexpensive and, because it is used as a paint thinner, can be found at most stores that sell paint. In Europe, it is more commonly known as “light petrol”. For a solvent to be 100% effective, it should be 100% pure. So use pure alcohol – it can be expensive and harder to find, though. Almost all of the solvents mentioned, including alcohol, are toxic, so it’s important that you follow the instructions for making cannabis oil carefully. Do not use ether or butane. While ether is very effective for this process, it is very explosive and is best used in laboratory conditions only. Butane is also very explosive and produces a less effective product. With a little research, you can find out more about powerful solvents that others have used successfully.

Wash the plant for the first time.

Place the dry plant buds in a large plastic bucket and add your solvent. Use a stick of clean, untreated wood to crush the buds and leaves. Then add more solvent to the bucket until the plant matter is completely covered and continue pounding for another 3 minutes. This is how the THC dissolves out of the plant matter and into the solvent. It is very important that this process is carried out in a well-ventilated area, away from cigarettes, flames, or sparks, as the solvent vapors are highly flammable.

Pour the solvent and oil mixture into another bucket.

Leave the hemp in the original container. At this point, 80% of the THC has already been released from the plants.

Wash the plants for the second time.

Add solvent to the plants again and stir for another 3 minutes to dissolve the remaining THC. When you’re done, add the solvent-oil mixture to the first mixture and discard the plant matter.

Filter your oil.

Take some empty water bottles and put a funnel in the neck of the bottle. Place a coffee filter in the funnel and pour the solvent-oil mixture through the filter to remove any unwanted plant matter.

Boil the solvent.

You’ll need to heat your mixture to cook off the solvent and leave only the oil. Fill a rice cooker three-quarters full and turn on the highest setting. Always keep an eye on the mixture as it cooks. As the volume of the solvent-oil mixture in the rice cooker decreases, add more of the mixture until there is nothing left. Again, it’s important that you do this work in a well-ventilated area, away from cigarettes, flames, or sparks, as the fumes are highly flammable. It is best to set up a fan to expel the fumes. A rice cooker works very well for this step of the process as it has a built-in heat sensor that prevents the rice from burning. In this case, it ensures that the temperature of your solvent-oil mixture does not rise too high. If this were the case, the cannabinoids would evaporate from the oil. The temperature should never rise above 140 °C.

Remove the last of the solvent.

When there are only about 2 inches of the solvent-oil mixture left in the rice cooker, you’ll need to add a few drops of water to cook off the remaining solvent. Once you’ve used 450 grams of plant matter, add 10 to 12 drops of water to the cooker. If you used 30 grams, you only need about two drops. When the remaining solvent has boiled away, the cooker should automatically turn to the lowest setting. If you’d like, you can put on a pair of oven mitts, lift the rice cooker, and swirl it around to aid in the evaporation process. The water causes the oil to bubble and crackle. There may also be some smoke or vapor, which is perfectly normal.

Let the water evaporate.

Put on your oven mitts and remove the inner pot of oil from the stove. Pour the oil carefully into a small stainless steel container. Place this container in a dehumidifier or on an easy-to-heat object, such as a hot plate or coffee warmer. When the oil stops bubbling, remove the container from the plate and let it cool down a bit. Depending on the type of plant material you used, the water can boil off very quickly, or it can take a few hours for the oil to stop bubbling.

Pack the oil for use.

Dip the tip of a plastic syringe into the oil and gently pull back on the plunger to draw the oil into the syringe and allow it to cool. You can also just pour the oil into a clean bottle instead of using a syringe, but the syringe makes it easier to dose the medication. Store the oil in a cool, dark place to keep it longer. The cold oil will form a thick mass and it may be difficult to squeeze it out of the syringe. Just run some warm water over the syringe to make the oil more liquid again.

Alternative method with olive oil

Heat 10g of organically grown and dried buds and the small leaves of medicinal cannabis (preferably a hybrid 80:20 Indica:Sativa) on a tray at 105ºC in the oven for 30 minutes.

Remove about half of the herbs from the oven.

Then increase the temperature for the other half remaining in the oven to 120ºC for another 30 minutes.

Take out the rest and now use a coffee grinder to grind the straw-dry material into a very fine powder.

Clean the grinder with a fine brush and use all the fine powder.

Mix it in a small saucepan with 100ml of extra virgin olive oil and put on the fire.

Slowly heat until slightly simmering, then reduce heat and let simmer on low for 9-10 minutes.

Stir it gently the whole time.

The color of the plant material changes from green to golden-brown. It also produces some fumes, don’t worry about that. Just make sure it doesn’t turn black or you’ll burn it.

Use a 3-way fractional extraction.

After about three minutes, strain out one-third; let the rest simmer for another three minutes, and again strain out a third. After the last three minutes, you take it off the fire for good. Let it cool for five minutes, then strain out the last third with a metal colander. Squeeze the oil out as hard as you can by pressing against the strainer with a teaspoon. The oil now contains terpenoids and all cannabinoids (THC, CBD, CBN, etc.) and is the best medicine ever.

Use the oil

The oil should be taken orally, preferably with some green tea and/or soy milk (cannabinoids are lipophilic). The dose to be used is therefore not exceeded. Start slow, with a drop of oil before bed. Be careful… take your time and slowly build a tolerance. The effect sets in after about 0.5 to 1 hour and lasts about 8 to 12 hours. Titrate the dose as high as you like, but wait at least 1 hour after a dose before taking another dose; the effect is cumulative.

Store the oil away from heat and light.

Keep it cool so it retains its freshness and potency.

Overdosing is impossible if you start slow, but if you’re feeling strange, drink some strong black coffee or just go to bed and relax or meditate for a bit.

Let the chi flow through your body; nothing can happen to you, just let go. The oil is non-addictive and there are no lasting effects like a “high” if the directions are followed closely. In the early stages of therapy, you’d better never take it before you intend to drive or operate heavy/dangerous machinery. Don’t worry, your body will develop a tolerance! Please note that you may have a Jarisch-Herxheimer reaction and/or an initial worsening of your symptoms, this is due to the medicinal effects of cannabis, it has anti-viral, anti-parasitic, anti-bacterial and some anti-fungal properties. It has a strengthening and harmonizing effect on the immune system within a short treatment period, but please be patient. The oil is also very good for local use, for skin cancer, exanthema, pruritus, burns, wounds, rheumatism, and warts.


The oil is intended for medical use only. The oil has been used to relieve the symptoms of anxiety disorders, bipolar disorder, colitis, diabetes, epilepsy, heart disease, multiple sclerosis, nausea, Parkinson’s disease, rheumatoid arthritis, schizophrenia, depression, liver inflammation, and cancer, neurological disorders, and neurological pain relief. Please note that you may have a Jarisch-Herxheimer reaction and/or an initial worsening of your symptoms, this is due to the medicinal effects of cannabis, it has anti-viral, anti-parasitic, anti-bacterial and some anti-fungal properties. So it can kill germs and their toxins can cause problems. It is, therefore, best to detoxify as best you can with green tea. It improves your overall immune system tremendously within a short treatment time, but be patient. The concentration of the oil can be increased by using more dried buds per 100ml of oil; It’s worth a try. Alternatively, you can simply use it as tea, but for this, you need to grind up 0.5 to 1 g of high-quality buds and boil them in a fatty substance, such as milk, for 10 minutes. Then mix the result with green or black tea and drink it. This is a convenient ingestion method.


Possessing or selling raw marijuana is illegal in most countries. Whole or raw marijuana (including marijuana oil or hemp oil) is only permitted if it is a finished medicinal product. It is not FDA-approved for medical use in the US.
